Primary Payload Container

Build Conventions When Discussing Payload Outer Container

Face A = Bottom
Face B = Top
Face C = Right
Face D = Back
Face E = Left
Face F = Front

For reference, if the container is resting on Bottom (Face A) and you are facing the Front (Face F) then Face C is on your right and Face E is on your left.

Attachments, Rigging and Wiring To/From Primary Payload Container

Top (Face B)
* Two Rigging Ropes to Cut-Down Device
* One Rope for Envelope Inversion Upon Cut-Down

Bottom (Face A)
* Four Rigging Ropes to Ballast Container
* One Sensor Line (temp. and humidity sensors on same line/multiple wires ???)
* Ballast Valve Power Line (two wires)
* Launch Confirmation Jack (two wires)


Ground Support Panel

  • Power Handoff Switch
    • Switches raw battery power between ground support source and internal batteries.
  • Ground Support Connection
  • Launch Confirmation jack pigtail

DB9 Plug Wiring Pinout

Pin # Function
1 3.3v pwr out
3 GSP VBatt
8 GSP VBatt
9 GSP VBatt

Note: The 3.3 volt line is actually sourced from the payload power controller. The ground support hardware is powered from the ground support batteries AFTER the power is routed through the payload power controller.
